[0024] Example 1

[0025] like Figure 1-Figure 3 As shown, the utility model provides a drone 1 detection system based on a gantry crane bracket 1, comprising a liftable gantry crane bracket 1, a drone 1, a dynamic capture device 3 and a data processing device;

[0026] In the technical solution, the gantry crane bracket 1 that can be raised and lowered simulates different test scenarios by changing different heights; the dynamic capture device 3 is a dynamic capture camera that can monitor the flight data of the drone 1 in real time, such as flight speed, flight altitude, attitude, etc. The drone 1 includes a frame 13, on which sensors and a data collector are installed. The data collector in this embodiment is a camera 14. A gimbal is installed at the bottom of the drone 1, and a camera 14 is installed on the gimbal. The camera 14 uses a Siyi ZR10 camera, which supports high-definition images and hybrid zoom. The camera 14 can monitor the defects on the surface of the gantry crane bracket 1, identify possible defects, and feed back to the data processing device through the data transmission module for subsequent processing by the operator.

[0027] A data transmission module is provided inside the frame 13 of the drone 1, and the sensors and data collectors are connected to the data transmission module; the data transmission module and the motion capture device 3 are both signal-connected to the data processing device, and the data information collected by the data transmission module and the motion capture device 3 is used to simultaneously evaluate the flight performance and operating efficiency of the drone 1, wherein the data processing device is a computer, mobile phone or tablet computer and other equipment.

[0028] Among them: the gantry crane bracket 1 is made of aluminum alloy material as a whole, and the gantry crane bracket 1 includes a bottom support frame 4, and a height adjustment frame is symmetrically installed on the top of the bottom support frame 4. A crossbeam 9 is connected and installed between the two height adjustment frames. The tops of the two sleeve rods 7 are welded through a crossbar, and a pull rod 10 is connected between the crossbeam 9 and the top of the sleeve rod 7. The crossbeam 9 is fixed by the pull rod 10. The height adjustment frame includes two sleeves 6, and a sleeve rod 7 is sleeved inside each sleeve 6. Positioning holes 8 are provided on the sleeves 6 and the sleeve rod 7. Positioning pins are provided in the positioning holes 8. The height of the sleeve rod 7 can be adjusted by adjusting the positioning pins, thereby adjusting the height of the crossbeam 9. In order to achieve the stability of the fixation of the crossbeam 9, a transverse support 11 is installed between the two sleeve rods 7. The transverse support 11 has two through holes. The sleeve rod 7 is inserted into the through holes. The inner wall of the through hole fits with the outer side of the sleeve rod 7, that is, the contour of the through hole is exactly the same as the outer contour of the cross section of the sleeve rod 7, and connecting plates 12 are symmetrically provided on both sides of the top of the through hole on the transverse support 11. The inner side of the connecting plate 12 fits with the side of the sleeve rod 7, and the transverse support 11 is fixed between the two sleeve rods 7 through the connecting plate 12.

[0029] A universal wheel 5 is installed at the bottom end of the bottom support frame 4 to facilitate the movement of the entire gantry crane bracket 1.

[0030] A plurality of motion capture devices 3 are evenly arranged at equal intervals around the gantry crane bracket 1 . The motion capture devices 3 use a VICON motion capture system to locate the UAV 1 .

[0031] In order to meet the requirements of the fuselage of UAV 1, carbon fiber sheets and nylon materials were selected for design and manufacturing. Carbon fiber, with its light weight and high strength, is an ideal choice for fuselage manufacturing, ensuring that UAV 1 has excellent stability and sustainability during flight. In order to ensure that UAV 1 can fly stably for a long time, it is equipped with a large-capacity six-cell lithium battery of 5300mAh. This battery not only provides sufficient power for UAV 1, but also supports a long battery life, making UAV 1 more reliable when performing complex tasks. In terms of control, the Pixracer R15 series flight control was selected. As the core of UAV 1, the flight control is responsible for receiving the instructions of the remote control and accurately calculating the corresponding control signals to transmit to the motor. In addition, the built-in WiFi module of the flight control enables the operator to monitor the flight status of UAV 1 in real time to ensure flight safety. In addition, the onboard computer uses UP Core Plus, and the system is Ubuntu20.04, which allows the aircraft to be further prepared for flight missions such as inspections.

[0032] The flight controller inside the UAV 1 has a built-in trajectory planning module, which obtains a safe and smooth trajectory and converts it into a control command by the flight control module. The flight control connection module is used to control the flight of the UAV 1.

[0033] During inspection, image data is acquired through the sensor and camera 14 at the bottom of the drone 1, and then transmitted to the data processing device through the data transmission module. At the same time, the dynamic capture device 3 positions the drone 1 for testing the autonomous planning performance of the drone 1, and the collected flight data (flight speed, flight altitude and attitude, etc.) of the drone 1 is fed back to the data processing device. The system realizes real-time detection and data analysis of the drone 1 in the gantry crane test scenario, and can efficiently test the autonomous planning performance and image capture performance of the drone 1 in the test scenarios of the gantry crane bracket 1 at different heights.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
